Overview

CVE-2022-49806 is a medium-severity vulnerability. It was published on May 1, 2025 and has a CVSS 3.1 base score of 5.5 (MEDIUM).

Technical description

In the Linux kernel, the following vulnerability has been resolved:

net: microchip: sparx5: Fix potential null-ptr-deref in sparx_stats_init() and sparx5_start()

sparx_stats_init() calls create_singlethread_workqueue() and not

checked the ret value, which may return NULL. And a null-ptr-deref may

happen:

sparx_stats_init()

create_singlethread_workqueue() # failed, sparx5->stats_queue is NULL

queue_delayed_work()

queue_delayed_work_on()

__queue_delayed_work() # warning here, but continue

__queue_work() # access wq->flags, null-ptr-deref

Check the ret value and return -ENOMEM if it is NULL. So as

sparx5_start().

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
